At-will employment doesn't matter. The suit can easily be filed based on grounds that the employees future work capacity has been materially damaged because the firing gave implicit truth to the accusations, whether they be true or not. In the United States of America anyone can sue anyone for anything. Once it gets to the court, everything is open to interpretation. Thats why most legal documents are written with vague language that leaves intent and outcome up to the interpretation of the court.
